<P>PROBLEM TO BE SOLVED: To provide a vibration motor and a mobile terminal device which can be easily manufactured and reduce a projection height from a substrate when mounted to the substrate, and a manufacturing method of the vibration motor. <P>SOLUTION: The vibration motor 1 has a motor housing 9 which is provided with one side projection part 31 and the other side projection part 33 arranged on a marginal part of an opening 27 formed on a substrate 2. The inner peripheral surface of the motor housing 9 is made of cylindrical magnetic material. The one side projection part 31 and the other side projection part 33 are arranged with intervals in a surrounding direction of the outer peripheral surface of the motor housing 9 and formed by making the wall part including the outer peripheral surface of the motor housing 9 deformed and projected outward. <P>COPYRIGHT: (C)2012,JPO&INPIT |
